To all whom it may concern;

Be it known that I, Lunvre A. IVERSON,

a citizen of the United States, residing at.

Lankin, in the county of Walsh, State of North Dakota, have inventedcertain new and useful Improvements in Grain-Treating Machines; and I doherebydeclare the following to be a full, clear, and exact descriptionof the invention, such as will onable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improved machine for treating grain toremove smut as well as to eliminate the production of smutty grain inthe resultant crop, the invention havin among its primary objects, toprovide a mac inc which will insure thorough treat ment with a minimumof cleansing fluid such as formaldehyde mixture; to efficientlydischarge the grain so treated and to permit detachment of certain. ofthe parts for cleaning when it is desired to treat different kinds ofgrain.

The invention further consists in an improved grain treating machine forthe purposes specified, which embodies a hopper to receive the grain tobe treated or c eaned, said hopper havinga discharge spout with meansfor controlling the feeding of the grain, said hopper being arrangedupon a support or table beneath which is disposed a trough for a spiralconveyer, while' i also supported on the table is a tank for containingthe fluid to treat the grain and from which the fluid is discharged todrop onto the grain as the latter is discharged into the trough, therebeing an opening in the tion, w

table through which the grain passes and in which is arranged in a novelrelation, a series of bafie walls which insure preliminary mixing sothat the grain will be thoroughly treated'in connection with theagitation thereof produced by operation of the conveyer.

With the above objects and others in view as will appearas thespecification proceeds, the invention comprises certain novelcombinations and arrangements of parts as will be hereinafter moreparticularly pointed out and claimed.

Reference is had to the accompanying drawi forming a part of thisapplicafiirein like characters designate cor- GRAIN-TREATING mourns.

- Fig. 2 is a verticallongitudinal sectional view thereof,

Fig. 3-is an end elevation,

4 is a plan view, Y

F1g. 5 is a transverse vertical sectional view, and a Fig. 6 is afragmentary bottom view. Referring to the drawings in detail, mylmproved grain treating machine comprises a hopper 10, the same beingsupported upon a table or platform 11 which extends beyond one end ofthe hopper at the end toward which the bottom thereof inclines. Thetable is arranged upon a suitable frame 12 supported by corner legs 13suitably secured to the frame, table or platform and the sides of thehopper 10. At the discharge end, the legs are connected by a cross brace14 beneath which is disposed. an inclined frame '15 extending frombeneath the extended portion of the table at the front end thereof andprotruding beyond the op posite end where it is provided with a crossmember 16. This frame is supported in conjunction with a wall ,17recessed as shown at 18 to receive the inclined frame sides, and alsoprovided with a substantial semicircular central recess 19 for receivingtherein removably, a trough 20 of corresponding cross section. Thetrough 20 is supported in the opposite end 21 of the frame through themedium of a recess 22 in a block 23-carried by the inner face of saidend wall 21 in which the adjacent end of the trough fits, the troughbeing further-provided with 'a depending lip 24 which facilitates itsretention in proper snug relation to said end wall and block. The troughis supported by a'slotted keeper late 25 su ported by the bottom edge ofthe lock and aving a gripping portion 26 by which it may be shiftedacross the slot to support or release the trough as desired. Journaledin the end wall21 and in the cross member 16 is a spiral 'conveyer 27the major portion of which is enveloped by the trough, which latter hasits sides extending considerably above the conveyer in order to preventthe grainfrom being discharged over the top edge of the trough, insteadof being carried to the lower end thereof from which the conveyerprojects and at which point sheet metal secured'to the bottom of the hopperadjacent to the opening to facilitate the discharge of the grain,jthespout projecting from the discharge end of the hopper and having flangedsides as shown. The spout also projects into an opening3l in the tableor platform forwardly of the hopper andthe discharge of the grain intothe spout is regulated through the medium of a slide gate 32 movable ina guide-way- 33 above the discharge opening, so that the properquantitiy ofgrain can be fed into the mixing Y device produced by thetrough and spiral conveyer therein, both of which are inclined towardthe discharge'end of the machine.

Disposed within the opening 29 is a lining 34 providing opposed bafiiewalls arranged in tortuous relation or staggered re lation at oppositesides of the opening beneath and opposedto the spout 30, the upperbafiie wall being in the form of a ledge 35 forming a-spreader for thetreating fluid such as formaldehyde mixture contained within a tank 36supported upon the projecting end of the table or platform and providedwith a valved outlet 37 controlling the discharge of said mixture. Itwill thus be seen that the mixture will be discharged onto the ledge orspreader surface and in this way, as the grain-is discharged it willstrike beneath said ledge, thereby insuring that the fluid willdropthereon and that the grain will be thoroughly treated on its way tothe conveyer in which it is subsequently further treated due toagitation produced therein and finally discharged. The above operationcan be carried on ma simple and eflicient manner and insures thoroughtreatment of the grain for smut. Owing to thenear its lower end, isanopening 40 covered by a screen 41, for drawing out surplus solution fromtime to time. This opening de-' liversinto a funnel 42 having avalve 43for controlling its discharge into a pail 44,011 asimilar receptacle.This detail is shown only in Fig. 20f the drawing and may be used or notat will.

What is claimed is In a grain treating machine, the combination with ahopper having a discharge opening and a grain conveyer and mixer locatedbelow the hopper, a spout mounted below the discharge opening, a guideplate in the discharge opening for directing the flow of grain to thecenter of the'spout, a liquid container mounted adjacent the dischargeopening and above the spout, and a horizontal plate mounted within thespout and extending transversely of the spout to receive thereon theliquid discharged from the said container, and to deflect the liquidacross the path of flow of grain from the hopper.

In testimony whereof, I afiix my signature, in thelpresence'of twowitnesses.
